ARTHUR LOPEZ, OF NEW YORK, N. Y., ASSIG-NOR TO THE HAMMOND TYPEWRITER 00., A CORPORATION OF NEW YORK.

DOUBLE-SHUTTLE ANVIL FOR TYPE-WRITING MACHINES.

Application filed July so, 1913. Serial n 781,959.

To all whom it may concern: Be 11; known that I, ARTHUR Lornz a citizen of the United States OI America, re-

, siding in New York, in the borough of Manhattan, county and State of New 'iork, have invented certain new and useful Improvements in Double-Shuttle Anvils for Type- Vriting Machines, of which the followlng is a specification. D

This invention relates to certain improvements in typewriting machines, and more especially to improvements in the Hammond typewriting machine in which two shuttles with different types or characters are arranged on' the anvil of the machine, one of said shuttles being placed into active position for printing and the other in inactive position. so that the machine can be used for printing in two different languages, or with different types.

The object of this invention is to provlde means for quickly changing one shuttle for the other without removing the shuttles ,from the anvil, whereby the usefulness of the Hammond typewriting machine is considerably enhanced and adapted to modern requirements; and for this purpose the invention consists of the novel features and combination of parts which will be full Y described hereinafter and finally pointed out in the-claims.

In the accompanying drawings, Figure 1 represents a plan-view of my improved attachment for typewriting machines, F ig. 2

is a vertical transverse section of the same on line 2-2, Fig. 1, Fig. 3 is a vertical longitudinal section taken on line 3-3, Fig. I, Fig. 4 is a detail plan-view, showing the connection of the shuttle with the shuttlelock bracket and one of the shuttle lifting' arms, Fig. 5 is a vertical transverse section figures of the drawings.

on line 5-43, Fig. 4, the last two [i ures being drawn on a larger scale, and ig. 6 is a detail section, showing the connect on of the radial arms with the anvil-shaft.

Similar letters of reference indicate cor responding parts throughout the different drawings, and more particularly to Fig. 1, the anvil a and the vertical shaft a of the same are shown, with the frame and the toplate 1 of the same by. which the anvil an shaft are supported.

Referring to th The shaft a of the anvil is guided inbear edf-"the-lower cross bar 0.? and uppercross-bar a." of the frame 7, as shown clearly in Fig. 2. Below the anvil a. is arranged the shuttle-arm b which turns freely by its center-sleeve b on a washer b on the crossbar of, and'which shuttle-arm is provided at the outer end with an upwardly-extending pm I)" vfor engaging the bushing d of the shuttle d, which is guided in a horizontal guide-slit a in the anvil, in the usual manner, so as to bring either one of the type represented on the shuttle into proper position for printing, according to the key which Is depressed. The anvil a is provided with two guide-slits a, one in its front and the other in its rear portion, and with two shuttles (Z the bushings d of which are guided on said slits, the bushing of one shuttle being connected with the locking pin 1) on the shuttle-arm in the well known manner, while the bushing of the other shuttle is connected with the inner upright pin 6 of a shuttle-lock bracket 0, which is attached at its outer end to the semicircular topplate f of the frame f and which surrounds the anvil on a level with the uide-slits, as shown clearly in Fig. 3. T e stationary shuttle-lock bracket 0 is arranged in line with the printing devices, the shuttle-shield s and hammer is, at a pointdiametrically thereto at the front-end of the supportin plate f and serves for locking the secon position by means of an upright locating Bin g, which is attached to the upper crossar a of the supporting frame f, and which engages oneof two sleeves 9'' that are formed in the diametrical cross-bar a of the anvil, one sleeve being used in connection with the upright locating pin g when the front-shuttle is used for printing, while the other sleeve is used in connection with the locating pin y when the anvil is reversed, so that the second or front shuttle is placed'in po.

sition for printing and the rear-shuttle placed into locked inactive position on the anvil. For locking one or the other sleeve 9 to the locating in g, the anvil has to be lifted clear above t e supporting plate, then turned for an angle of 180, so that the change of position of the shuttles-on the same is accom lished. For thispurpose, are arranged on- -t eshaft of the'anvil, adiacent tothe hub of thean ii,

lifting arms h which are curved in downward direction so as to extend under the bushings of the shuttles, said arms beingprovided with concave ends h so as to surround the guide-sleeve d in each bushing when the anvil-lifting arms h are raised, said arms having a slight play in upward direction by means of a helical cushioning spring h which is placed around the upper end of the shaft of the anvil and interposed between the socket k of the radial-arm support it having the knob or button h and a disk h attached to the upper end of the shaft a. The amount of movement of the supporth on the anvil-shaft a is such that the anvil can be lifted suiliciently above the surrounding top-plate f for permitting the turning of the anvil on its axis and the reversing of the shuttles, that is to say, the rear-shuttle to the front and the front-shuttle to the rear of the anvil and vice versa. The sleeve-shaped support it from which the anvil-lifting arms are extended is guided at the upper end of the shaft a by a pin or' key It which slides in a vertlcal recess h in the upper end of the shaft, as

shown clearly in ,Fig. 6, said key preventing the aizial motion of the anvil-lifting arms h on the shaft a when iving the support 72, a short vertical play or placing the anvillifting arms first into contact with the bushings of the shuttles'and then lifting the shaft a? with the anvil a into position above the top-plate f of the machine, as shown clearly in dotted lines in Fig; 3. The springcushioned support h permits the dividing of the lifting motion into two partsfirst, into lifting motion so as to bring the anvil-lifting arms into contact with the bushings of the shuttles and, secondly, into the lifting motion-for the anvil itsel I The anvil is held in its normal position relatively to the surrounding top-plate f b a stationary post i which is screwed into tlie'cross-bar a of the frame f, as shown clearly in Fig. 1, said post engaging the diametrical arm a of the anvil, while the locating pin 9 engages one of the sleeves in the diametrical arm of the anvil on the side opposite to the 0st z'. When the anvil and its shaft are p aced in proper position in the hearings of the supporting frame the anvil is supported on one side by the upright locating pin 9 and one of the sleeves g in its diametrical' arm a and on the opposite side by the stationary post 2', as shown clearly in Fi 2. The lower end of the shaft a of t e anvil is provided with a groove a in which engages a horizontallyisposed lever I having a bent inner end and a handle at its outer end, and which extends iii-lateral direction from the shaft 0: and is so po mi by a collar Z on a fixed upright lro Z that is Supported inthe lower and upper moss-bars of the heme f, a helical spring Z being interposed between the upper cross-bar and the lever Z, so that the lever I can follow the up and down motion of the of the anvil and change the position of the shuttles on the same from their active position to the inactive position, and vice versa, the shuttles are placed in symmetrical posi tion, relatively to the vertical longitudinal plane of the machine, indicated by the section-line 83, Fig.1, at the front and rear portions of the anvil, after which the knob of the anvil-shaft is lifted so as to bring the anvil-lifting arms under the bushings of the shuttles (Z, as shown in Figs. 4 and 5, and then lift the anvil with "the shuttles by the shaft (1 and horizontal lever 1 against the tension of the spring Z into raised position above the top-plate f ,'as shown in dotted lines in Fig. 3, in which position the anvil with its shaft and the shuttles can be turned around until the opposite sleeve 9 in the diametrical crossbar of the anvil can be placed over the stationary locating pin 9, so that the anvil can be locked by the same on lowering it, whereh the position of the shuttles is reversed an one shuttle placed into active or printing position at the rear and the other shuttle is placed into inactive position at the front of the anvil. In lowering the anvil,-care has to be taken thatthe uidesleeve (5 in the bushing of the active s uttle engages the engaging pin on the shuttle-arm and that the guide-sleeve d in the bushing of the other or inactive shuttle is placed over the locking pin of the shuttle-lock bracket and the inactive shuttle locked into position, while the active shuttle is capable of being operated in the usual manner by placing either one of its type or characters into its proper position for printing. The diamtrical anvil-lifting arms serve for engaging the bushings of the shuttles when the bnshin s are alined in the longitudinal axis of the machine so as to hold the anvil, release the bushings of the shuttles from the locking pins on the shuttle-arm and shuttle-lock bracket, and remove the diametrical arm of the anvil from the locating pin, and then lower the anvil after it is reversed and rethe shaft, so that the entire anvil can hereiao moved from the machine for cleaning, repairing or other purposes.

hen it is desired to remove any one of the shuttles and replace it by a shuttle of different type or character, the anvil is lifted sufficiently until the bushings on the diametrinecessitating the time-consuming exchange of the shuttle on the anvil with an extra shuttle and the restoring of the original shuttle when the extra shuttle is not desired for use. By the duplex arrangement of shuttles one or the other is immediately ready for use, by simply lifting the anvil to the proper height, reversing its position, and then returning it into its locked position by the shuttle-lifting arm with the shuttle-bushings into locked position on the pin of the shuttle-arm and the locating pin on the shuttle-lock bracket.

All the advantages that result from the exchange of shuttles are still retained, while the range of use of the typewriting machine is greatly enlarged and adapted to the requirements of correspondence, either bychanging a shuttle of one kind oftype or character to another, or from one language to another, and for other purposes. The other accessories, namely, the ribbon-guide and spools, shield, the reciprocating ham mer and the other accessories, are the same as in the Hammond typewriting machine at present in use.

In case correspondence is to be carried on in more than two different languages, a sec-. ond and even a third anvil, with two shuttles on each anvil, can be used and thereby many emergencies of commercial life, especially in foreign countries, be efiiectively provided for. y I

I have shown and described one embodiment of my invention, but it is clear that changes may be made therein without departing from the spirit of my inventlon, as described in the appended claims.

I claim:

1. In a typewriting machine having an anvil-shaft, an anvil and two shuttles thereon, the combination of radial arms extending from the anvil-shaft toward the shuttles, and means for supporting the radial arms so that the ends of said arms are normally out of engagement with. the shuttles, said means being movable on the anvil-shaft for bringing the radial arms into locking engagement with the shuttles.

2. In a typewriting machine, the combination of the anviLshaft, two shuttles, radial arms-supported by the anvil-shaft and movable thereon, the ends of said radial arms being normally below and out of engagement with said shuttles and capable of movement on the anvil-sl'iaft into engagement with the shuttles for locking the same when the anvil-shaft with the shuttles is raised, the shuttles transposed and the anvil-shaft with the shuttles again lowered, and means for returning the radial arms to normal position out of engagement with the shuttles.

3. In a typewriting machine having an anvil-shaft, an anvil, two shuttles on the anvil, a shuttle-driving arm engaging one shuttle and a fixed pin engaging the other shuttle, radial arms the ends of which are adapted to engage both shuttles and are normally out of engagement with the same, a knob connected with the radial arms on the anvilshaft for raising the radial arms into engagement with the shuttles, and raising the anvil-shaft with the anvil and shuttles out of one position and transposing the same into another position, and again lowering the same into desired position, and means for returning the knob with the radial arms into normal position out of engagement with the shuttles.

4e. In a typewritingmachine, an anvilshaft, an anvil thereor and two shuttles on the anvil. a plate at the upper end of the anvil-shaft projecting over the sides there of. a support movable on the anvil-shaft and provided with a socket at its upper end of slightly larger diameter than the plate on the anvil-shaft, arms extending rigidly away from the support toward the shuttles of the anvil, a spring interposed between the support and the pla e, and a knob for the open upper end 0 the socket and secured to the support. I

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
